Composite ferrite material as well as preparation method and application thereof
The invention provides a composite ferrite material as well as a preparation method and application thereof, and the preparation method comprises the following steps: (1) mixing a barium source and an iron source raw material to obtain a first mixture; mixing a barium source, an iron source and a substituted metal source raw material to obtain a second mixture; independently and sequentially carrying out pre-sintering, compression molding and primary sintering on the obtained first mixture and the second mixture to respectively obtain an M-type ferrite precursor and a Y-type ferrite precursor; and (2) mixing the M-type ferrite precursor and the Y-type ferrite precursor obtained in the step (1), carrying out secondary sintering treatment, crushing, annealing, and carrying out ultrasonic treatment to obtain the composite ferrite material, wherein the molar weight of the Y-type ferrite precursor is greater than that of the M-type ferrite precursor. The composite ferrite material disclosed by the invention is a composite ferrite material in which Z-type ferrite and Y-type ferrite coexist, and can give consideration to both low dielectric constant and high magnetic conductivity.
本发明提供了一种复合铁氧体材料及其制备方法和应用和应用，所述制备方法包括以下步骤：(1)将钡源与铁源原料混合，得到第一混料；将钡源、铁源和取代金属源原料混合，得到第二混料；将得到的第一混料和第二混料独立地依次进行预烧、压制成型以及一次烧结，分别得到M型铁氧体前驱体和Y型铁氧体前驱体；(2)将步骤(1)得到的M型铁氧体前驱体和Y型铁氧体前驱体混合后进行二次烧结处理，破碎后进行退火，经超声处理得到所述复合铁氧体材料；其中，所述Y型铁氧体前驱体的摩尔量>M型铁氧体前驱体的摩尔量。本发明所述复合铁氧体材料为Z型铁氧体与Y型铁氧体共存的复合铁氧体材料，可以兼顾低的介电常数和高的磁导率。
